Claims. l

This invention relates to bearing brackets and particularly to the type adaptable for mounting the rotatable shafts of air impellers on blower housings.

The primary object of this invention is to provide a combination socket and support therefor which is able to neatly receive and contain the bearing elements and capable of being quickly and easily assembled and attached to a supporting base.

Another object is to construct a combination device of the type mentioned that may be quickly and easily stamped out of sheet material and which may then be economically rolled and formed into light weight but sturdy streamlined supports.

These and other objects of the invention will become apparent from a reading of the following description and claims, together with the accompanying drawing, in which like parts are referred to and indicated by like reference characters and wherein:

Figure l is a View of a bearing bracket mounted on the side of a centrifugal blower;

Figure 2 is an elevation of the inside of the bearing bracket;

Figure 3 is a side View of the same, with parts of the socket portion broken away;

Figure 4 is an elevation of the outside of the bracket and socket;

Figure 5 is an enlarged View of the device taken substantially along the line and in the direction of the arrows 5 5 of the Figure 2, showing the shaft and bearing elements therein and particularly showing the lubricating members and means;

Figure 6 is an enlarged vertical cross sectional View of the bearing socket assembled and showing the shaft and bearing elements contained therein;

Figure '7 is a plan view of a removable ring used to close the socket and which retains the bearing elements; and

Figure 8 is a side view of the socket, particularly showing the notch therein which receives the projecting lubricating means.

In the Figure 1 there is shown a bearing bracket made in accordance with this invention. It has broadly an annular socket 2I, laterally extend- .ing arms 26 and ila-red ends or ears 28 mounted on the housing Ill.

Conducive to a clearer understanding of the invention, it may be well to first describe the bearing elements for which this bracket is designed. However, it should be understood that no invention is claimed in the bearing elements per se.

The rotatable shaft II has a short collar or porous metal bushing i2 loosely fitted around the end thereof which is to be supported. This bushing may be made of various metals capable of being permeated with a lubricant. Such bearings are commercially available and are well known in the art.

The lubricant holder is a cast iron ring I3 which has an annular hollowed portion or chamber i4 around the bushing I2. A short tube or neck I5 projects outwardly from the ring I3 and has a longitudinal passage I6 through which a lubricant may be fed into the hollow chamber I4. This may be closed by any suitable means to prevent leakage. The ring I3 is tightly fitted around the bushing I2 intermediate the ends of the latter member.

The circular rubber container Il' completely surrounds the iron ring I3 as is clearly shown in the Figures 5 and 6. However, it does have an opening I8 therein for the passage of the lubricating tube I5. The inner edges of the rubber container I1 t closely around the bushing I2 and it thus absorbs practically all vibration of the shaft II, the bushing I2, and the lubricating ring I3 and prevents the shock, Vibration or noise from being transmitted through the hereinafter described bracket to the housing IIJ.

The bracket member which consists of the annular socket 2l and the arms 26 is made of sheet metal. is made is stamped, rolled and bent to the shape shown.

The socket 2| is somewhat cup-shaped and has an opening 22 in the cup bottom through which the free end of the shaft II may project. This opening 22 is slightly larger than the diameter of the shaft II to permit free and unhindered rotation.

The edge or brim of the cup-like socket 2| has inwardly bent tabs 23 which receive the hereinaiter described notched ring 3l. A small opening or notch 24 is cut or stamped in one side of the socket 2| to accommodate the lubricating tube I5. This small opening is formed at the brim of the'socket and is open at the edge to permit the easy insertion of the tube I5.

The arm portions 26 are formed and rolled so that their longitudinal edges 21 abut each other and thus form tubular elements which are streamlined or aerodynamic in cross section, as is clearly indicated in the Figure 5 of the draw- The blank form from which it hold the ring 3l in place.

ing. The arm portions 23 extend, When mounted, across the mouth or air intake opening 20 of the blower IU, as is clearly shown in the Figure 1. The streamlined arms provide a smoother flow of air into the blower. An unbroken stream of air which is free from annoying turbulence is thus secured. Vibration and noise are reduced to a minimum.

The inner ends of the arms 26 flare and expand to partially form the heretofore described socket 2| and open therein, as is clearly shown in the Figures 2 and 3. The outer ends of the arms 26 are opened and flared and also drilled or punched to form neat and convenient means for attachment to the base I0. The Figures 2, 3 and 4 clearly show how the ends of' the arms are formed for easy mounting of the bracket. In the drawing, Figure 3, the reference character 25 indicates a conventional screw which may be used for mounting the bracket.

The sealing ring 3l is also stamped out of sheet metal. Its outside diameter is slightly smaller than the inside diameter of the socket member 2|. Its inside diameter is a little larger than the outside diameter of the bushing i2.

It has notches 32 around its peripheral edge through which the tabs 23 on the socket may i freely pass. It also has a small inwardly extending tab 33 which may be used as a convenient grip for either assembly or disassembly of the bearing elements and bracket. This tab 33 is short enough so that it does not touch or bind with the bushing I2,

During assembly and after the bearing elements l2, I3 and Il' are assembled and mounted on the shaft Il, the socket 2l is slipped over the resilient member Il and so that the lubricating neck I5 passes through the notch 24. The ring 3| is then passed over the bushing i2 and inserted into the socket against the flat face of the rubber -i container Il and turned slightly by means of the tab 33. The tabs 23 then engage unnotched portions of the edge ofthe ring 3i and the tension and resiliency of the rubber container i7 firmly If desired, the unnotched portions of the edge of the ring 3| may be recessed or formed with shallow depressions to more rmly engage the tabs 23 and thus prevent accidental unlocking of the elements.

Having thus disclosed the invention in its preferred form, it should be understood that the description and illustration herein should not be considered in a limited sense as there may be otherforms or modifications of the device which might also be reasonably held to come within the scope of the appended claims.

"I claim:

1. Abearing bracket, comprising in combination, a socket member capable of receiving shaft bearing means and having tubular arm portions integral therewith and opening thereinto, and a separable ring member mounted on the socket member capable of retaining the shaft bearing means therein.

Uil

2. A bearing bracket, comprising in combination, a socket member capable of receiving shaft bearing means, the said socket member having inwardly extending tabs on the brim thereof and also having laterally extending tubular arm portions, the said arm portions having flared ends and attachment means thereon for mounting on a base, and a separable ring member mounted on the aforesaid tabs and being capable of retaining the aforesaid shaft bearing means in the socket member.

3. A bearing bracket of the type defined in claim No. 2 and further characterized by the said socket member having an opening therein for the extension therethrough of a lubricating element for the bearing means.

4. In combination with a bearing for a rotatable shaft of the type having a lubricant permeable sleeve, a lubricant chamber around the sleeve and a resilient element surrounding the chamber; a bracket, comprising an annular socket member having tubular arms integral therewith, the said socket member containing the aforesaid sleeve, chamber and resilient element and having spaced tabs on the brim thereof, the said arms opening into the socket member and having flared ends and attachment means thereon for mounting the same on `a base, and 'a'ring member mounted in the said socket member and engaged by the said spaced tabs and being capable of retaining the aforesaid sleeve, chamber and resilient element in the socket member.
